Waste fluid flow control element

ABSTRACT

Waste fluid absorption devices, including sanitary napkins, tampons and baby diapers, comprising coplanar multiple ply of thin absorbent tissue paper, are impregnated in selected exterior border areas with non-toxic, waste fluid repellant compositions. The repellant compositions are applied in the minimum concentrations necessary, and produce separate and discrete tissue paper plies which are not easily wet by menstrual and urine fluids. Sanitary napkins comprising coplanar multiple ply of tissue paper disposed in an elongated pattern are impregnated at the exterior border planar area of the napkin, typically for a border area of 1/8 - 1/4 inch width disposed around the menstrual fluid absorptive section. A menstrual tampon comprises coplanar multiple plies of absorbent tissue paper formed into a compressed cylindrical tampon. The tampon end opposite the insertion end of the tampon is impregnated with a menstrual fluid repellant composition, in a concentration sufficient to prevent menstrual fluid flow through the interstices of paper plies of the tampon. The baby diaper is impregnated along the absorbent pad diaper edges.

No. 720,500, filed Apr. 11, 1968, nowU.S. Pat. No. 3,532,097 and to the copending application Ser. No.742,922, filed July 5, 1968, now U.S. Pat. No. 3,593,717 all relating toimprovements in sanitary napkins taught by this inventor. Thisapplication relates to the copending application on the improvements inmenstrual tampons, Ser. No. 720,501, now U.S. Pat. No. 3,610,243 filedApr. 11, l968 by this inventor. This application also relates to theU.S. application of this date titled OPTIMUM PROFILE DIAPER PAD.

BACKGROUND OF THE INVENTION Commercially available sanitary napkinscomprise menstrual fluid absorptive sections of fluffed, bleached woodpulp. The face of the sanitary napkin wood pulp pad disposed distantfrom the body surface in use is typically covered with a very thinpolyethylene film. Likewise separate thin polyethylene films cover thetwo long sides of the sanitary napkin pad, as it is normally disposed onthe female torso. These thin films of polyethylene, or the like plastic,control the flow of menstrual fluid, preventing the fluid from exudingfrom the absorptive wood pulp section and soiling the wearers clothesand the like. The fluffed and spongy dry wood pulp behaves in somemechanical aspects as a typical sponge, absorbing menstrual fluid andthen releasing the fluid when the wood pulp absorptive section iscompressed, as by body movement. In contrast, the multiple plies ofabsorptive tissue paper, having considerably smaller cellular dimensionswith respect to air space, do not behave as a typical sponge, for theyretain the menstrual fluid on absorption. In the menstrual sanitarynapkins of the inventions listed above, the exterior border planarvolumes of the coplanar multiple plies of tissue paper can be formedinto menstrual fluid repellant volumes without destroying the softness,flexibility and feel-to-the-skin of the tissue paper stock contained inthe napkins.

The commercially available menstrual tampons comprising cotton and rayonfibers are effective absorbers of menstrual fluid. However, also actingmechanically as sponges, they can release menstrual fluid on bodymovement. It is desirable to provide a menstrual fluid flow controlelement for the tampon positioned in use, which would prevent leakage ofthe menstrual fluid from the tampon end nearest the vaginal opening. Itis well known that babies excrete urine while lying in a variety ofpositions in a crib. Disposable, single use diapers can have fluffedbleached wood pulp and tissue sheet stock waste absorbent padcombinations. It is very desirable to provide a waste fluid flow controlelement along the exterior edges of the waste absorbent pad, to controlthe direction of flow of urine and the like. As disposable diapers arenow manufactured, it is very useful to provide a waste fluid controlelement along the two waist band edges of the diaper, as made in thecross-reference patent application.

SUMMARY OF THE INVENTION Menstrual fluid flow control elements aretaught for the sanitary napkins and the tampons having multiple plies offluid absorbent tissue paper. The normal tissue paper stock has amicroscopic cellular structure much smaller than that of conventionalfluffed, dry bleached wood pulp used in commercial sanitary napkins, andthat of cotton and rayon fiber structures used in conventional menstrualtampons. The exterior border planar area of elongated menstrual sanitarynapkins having coplanar multiple plies of absorptive tissue paper, ascross referenced above, have menstrual fluid flow control elements.Likewise, the menstrual tampons, as cross referenced above, comprisingcoplanar multiple plies of absorptive tissue paper, has the tampon endopposite the insertion end formed into a menstrual fluid flow controlelement. The disposable baby diaper pad has tissue paper sheet above orin combination with fluffed wood pulp, to form a waste absorbent pad.The pad can have a fluid flow control element disposed along the edgesdevised to encircle the babys abdomen, as well as along the longitudinaldiaper edges which encircle the baby s thighs.

The waste fluid flow control element is formed by treating the requiredgeometrical volume portion of the napkin and tampon with a non-toxicmenstrual fluid repellant composition which does not substantiallymodify the texture or the feel-to-the-skin of the separate plies oftissue paper stock. Typically the repellant impregnant can benon-volatile dimethyl polysiloxane fluids; non-volatile polyfluorocarbonfluids; nonvolatile hydrocarbon oil fluids; non-volatile fluid longchain fatty acid alkyl esters, and non-volatile mono, di andtriglyceride esters of long chain fatty acids; the zinc, calcium,magnesium and aluminum salts of long chain fatty acids; and the mixedcompositions of said esters of long chain fatty acids and glycerides andsaid salts of said fatty acids. The non-toxic fluid repellant impregnantcan be applied to the required napkin, tampon and diaper volume by aprinting process such as gravure or the like, or by spraying, or by rollcoating.

Included in the objects of this invention are:

First, to provide waste fluid flow control elements for multiple ply,absorptive tissue paper sections of sanitary napkins, tampons anddiapers.

Second, to provide a simple process for manufacturing waste fluid flowcontrol elements in sanitary napkins, tampons and diapers havingcoplanar multiple ply, tissue paper menstrual fluid absorptive sections.

Third, to provide waste fluid repellant elements for sanitary napkins,tampons, and diapers, having coplanar, multiple ply absorptive tissuepaper sections.

Fourth, to provide waste fluid repellant compositions for the requiredexterior border areas of sanitary napkins, tampons and diapers.

Further objects and advantages of this invention will become apparent inthe following description, to be read in conjunction with theaccompanying drawing.

DESCRIPTION OF THE PREFERRED EMBODIMENT napkin l. The multiple menstrualfluid reservoirs 5 are symmetrically disposed about the center line 16and the section line 2-2, as taught in the above application. In theplanar view of FIG. 1, the menstrual fluid flow control element 6 isshown disposed inside and adjacent the exterior edge 7 of the napkin 1,and 6 is also continued around and adjacent to the pair of slot openings4. The dotted line 8 denotes the interior edge of the menstrual fluidflow control element6, and the opposed pair of dotted lines 9 denote theexterior edge of the menstrual fluid flow control element 6 disposed inthe interior of the napkin adjacent the pair of slotted securingopenings 4. The planar border area 10 of the menstrual fluid flowcontrol element 6 has a thickness depth 11 further illustrated in crosssectional view in FIG. 2. Thus collectively the border volume enclosedby the planar border area 10 and the thickness depth 11 form the volumeof the menstrual fluid flow control element 6. The interface bond means12, shown in FIG. 2, secures the thin impermeable plastic film l3, bothof which are taught in the above listed patent applications.

. As is illustrated in FIG. 1, both opposed napkin tips 14 are excludedfrom the menstrual fluid absorptive section 15, which lies inside theinterior edge 8 of the menstrual fluid flow control element 6.

In a further embodiment of the menstrual fluid flow control element,FIG. 3 illustrates the menstrual fluid flow control element G'hxtendingaround the complete exterior edge 7 of the sanitary napkin 1. Thus themenstrual fluid absorptive section 15 is formed from all of the coplanarmultiple ply tissue paper 2 which lie inside of the menstrual fluid flowcontrol element 6'. The exterior planar border area 10' of the flowcontrol element 6 extends completely around and inside of the exterioredge 7 of the sanitary napkin 1'. The adhesive plug bonding means 3' andthe napkin securing slot openings 4' are disposed inside the interioredge 8' of the flow control element 6.

Referring to the cross sectional view of FIG. 4 in detail, the coplanarmultiple ply tissue paper 2" is shown to have a menstrual fluid flowcontrol element 6". The fluid flow control element 6" is formed in thevolume contained by the exterior planar border area 10' integrated overthe thickness depth 11''. The major thickness depth 1 l is shown toextend from the exterior absorptive surface 18 of the napkin, partiallythrough the complete thickness 17 of the coplanar multiple ply tissuepaper 2". As in the napkin 1 shown in cross sectional detail in FIG. 2,the cross sectional illustration of FIG. 4 shows the interface bondingmeans 12" securing the thin impermeable plastic film 13". In functionaluse the exterior absorptive face 18 of the type of a napkin l, or thelike, is the face through which menstrual fluids are typically initiallyabsorbed. Since the menstrual fluid flow control element 6" extends fromthe absorptive face 18 of the napkin through a major proportion 11" ofthe thickness 17 of the coplanar multiple ply tissue paper 2", the fluidflow control element 6" will direct the flow of menstrual fluidinteriorly into the menstrual fluid absorptive section 15", or the like,of the typical sanitary napkin l" or the like. Therefore, the spread ofabsorbed menstrual fluid will be directed primarily into the interior ofsection 15" by the capillary processes which control flow of fluids inporous paper stock, and will be restrained from moving toward theexterior edge 7", or the like, of the sanitary napkin, even though thefluid flow control element 6" extends only over a major proportion 11"of the thickness 17 of the sanitary napkin.

Referring to FIG. 5 in detail, the coplanar multiple ply tissue papertampon 50 is shown disposed in a standard paper exterior applicator tube51. The withdrawal string 52 is shown looped around the U-end of thetampon 50 forming the two legs 53 and 54 of the paper tampon 50. Thetampon end 55 is designated the insertion end, as it is normally firstinserted into the vaginal opening. The tampon end 56 is designated thetampon end opposite the insertion end 55. A menstrual fluid flow controlelement 57 is formed in the exterior volume of the tampon end 56 byimpregnating the surface portion of the tampon end 56 with the non-toxicwater repellant impregnant, in full equivalence to the menstrual fluidflow control impregnants discussed above. The water repellant impregnantmay be applied to the tampon, after the tampon is disposed in theapplicator tube as by spraying, or roll coating, or adding a drop ofimpregnant to the tampon end 56, or the like. Typically 0.05 to 0.15 g.of impregnant is useful.

It is obvious that when the tampon 50 is inserted into the vaginalopening in the normal functional position, the menstrual fluid flowcontrol element 57 will prevent leakage of menstrual fluid from thetampon as it will tend to prevent menstrual fluid being squeezed fromthe tampon 50 through the element 57, as by body motion.

Referring to FIG. 7 in detail, the disposable diaper 70 has a wasteabsorbent pad 71 cooperatively symmetrically disposed on a waste fluidimpermeable plastic membrane 72. The pair of longitudinal membraneborder seals 73 and 74 are formed by folding over the wider membranewidth on to the absorbent pad 71 and forming the seals 73 and 74,securing the pad 71 in position. The infant waist encircling diaper ends75 and 76 have waste fluid flow control elements 77 and 78 disposed inthe waist band sections 79 and 80, as earlier taught above for sanitarynapkins and tampons. When the improved infant diaper is suitablycooperatively secured on an infant with the waist band sections 79 and80 encircling the infant, the waist fluid flow control elements 77 and78 will greatly impede the flow of urine around the infants waist whilethe infant is lying down in the crib or being held in someones arms. Thewaste fluid flow control elements can also be disposed in the absorbentpad 71, as a pair of elements 81 and 82, closely adjacent and parallelto the longitudinal membrane border seals 73 and 74, providingadditional protection to urine and feces flow around the infants legs.

In its general embodiment, the waste fluid flow control element 6, orthe like, comprises two components. The first component is a suitabledisposed volume of coplanar multiple ply of tissue paper of anabsorptive non-calendared tissue paper stock of a suitable width anddepth to form an exterior edge volume, and the second component is awaste fluid repellant composition reasonably uniformly disposed in thedesignated first component absorptive section volume. Briefly the wastefluid flow control element comprises the border planar volume of themultiple ply of tissue paper absorptive section and a nontoxic menstrualfluid repellant impregnant disposed in the exterior planar border volumeof the absorptive pad. Specifically, the nontoxic waste fluid repellantimpregnant is of a character which wets and impregnates the porousuncalendared tissue paper stock in the separate, individual, discretepaper plies, without bonding the plies together in a laminated type ofmechanical structure. The impregnant is specifically provided to preventthe waste fluid from wetting and going through the waste fluid flowcontrol element. At the same time it is provided that the waste fluidrepellant impregnant will not destroy the softness, flexibility andsoftness of touch to the skin necessary to prevent chafing of the bodyskin in contact during movement.

Non-toxic waste fluid repellant impregnants which are suitably usefulare as follows:

' l. nonvolatile dimethyl polysiloxane fluids, manufactured forwaterproofing paper stock.

2. nonvolatile polyfluorocarbon fluids, manufactured for waterproofingpaper stock.

3. zinc, calcium, magnesium and aluminum stearates dissolved in liquidhydrophobic, non-volatile bases, such as butyl stearate, refinedbleached mineral (USP. XV-l955), refined corn oil and other refinededible oils and modified mono and diglycerides, alkyl stearates and thelike esters of long chain fatty acids. The above listed types ofnon-toxic, non-volatile, liquid hydrophobic oil bases are substantiallyimproved by the addition of the listed metal stearates, in typicalconcentration ranges of -90 wt percent. The solutions can be used hot,to provide the desired metal stearate concentration. Other non-toxicmetal salts of other long chain fatty acids may be used, but watersoluble foam ing soaps should be avoided.

Other suitable menstrual fluid repellant compositions may be used asimpregnants. characteristically the menstrual fluid repellantcomposition should be non-toxic and water repellant or hydrophobic. Themenstrual fluid repellant should be either a liquid at room temperature,or be a high melting lubricant solid such as zinc or magnesium, or thelike stearate, which will not fuse on standing in commercial storage toform a waxlike, fused solid. The repellant should not bond the multipleplies of tissue paper together into a laminated mass.

The fluid repellant composition can be applied to form the menstrualfluid flow control element by spraying, roll coating or by a printingprocesson a napkin 1 or the like. FIG. 6-illustrates a perspectiveelevation view of a printing frame shaped to provide the configurationof the menstrual fluid flow control element 6 of the sanitary napkin 1.As is well known, the printing face 61 of the printing frame may have asurface gravure configuration adapted to provide the required amount ofa menstrual fluid repellant composition on the printing face to beapplied to a specific sanitary napkin or its separate plies. Thus inprinciple the sanitary napkin l, or the like, may be cut into shape froma raw stock of coplanar multiple plies of tissue paper, andsimultaneously may be printed within the exterior edge of the newly cutsanitary napkin to provide the menstrual fluid flow control element 6,or the like. By controlling the gravure configuration on the printingface 61 of the printing frame 60, and by simultaneously controlling theviscosity of the menstrual fluid repellant composition being applied tothe printing face 61, it is possible to vary the quantity of repellantcomposition to provide the required structure of the menstrual fluidflow control element 6.

By selecting and controlling the application method or process; theviscosity of the repellant fluid composition or the particle size of theapplied zinc stearate, or the like metal soap; and the amount ofrepellant composition applied; it is possible to control the width ofthe exterior planar border area 10 and the depth or thickness 11, of themenstrual fluid flow control element 6, or the likes, in other napkins.Typically the width of border area 10 can range from one-eighth toone-fourth inch. The depth or thickness 11 of the element 6 can rangetypically from all tissue plies to twothirds of the plies, or the like.

The weight of the menstrual fluid repellant composition which is appliedis that amount required to produce the desired volume of the menstrualfluid control element. Typically, a 50 wt percent of zinc stearate (USP)dissolved in hot butyl stearate solvent (cosmetic grade) was sprayed,while hot, on stacked napkins. The napkins were vertically stacked withthe absorptive section 15 of one napkin 1 adjacent to the plastic film13 of another napkin 1, the napkins 1 being coaxially aligned on thecenter lines 2-2 and 16. The weight of the above impregnant compositionapplied to each napkin l, forming an element 6', or the like, was about0.5 g. On testing the border menstrual fluid control element with acolored aqueous dye solution, the control element 6', or the like, wasclearly dye impervious for the full thickness of the depth 11, or thelike, and the width of border area was approximately 3/16 to 34; inch.Fused zinc stearate, magnesium stearate, or other low melting waterinsoluble, non-toxic metal fatty acid salts can be sprayed or rollcoated as the impregnant in the element 6', or the like.

The 25 wt percent solution of zinc stearate in butyl stearate isdesirable due to low cost, fluid impermeability, and nontoxic nature.Other water repellant fluid impregnants, vsuch as the waterproofingdimethyl polysiloxanes and polyfluorocarbons may be applied, at typicalconcentration as required on the weight of a napkin. Zinc stearate alonemay also be impregnated in the edge of a napkin to form a useful flowcontrol impregnant. The chromium (Cr complex of N-ethyl-N-heptadecylfluoro-octane sulfonyl glycine aqueous solution (0.7 wtpercent), also containing 2. wt percent urea, was sprayed on the edgesof vertically stacked napkins, as described above. The weight ofimpregnant of the above chromium complex after drying was 0.0035 gram onthe total napkin weight of 8.0 g, disposed in a 3/ l 6% inch widecontrol element 6', or the like. The test of the napkins with thesimilar aqueous dye solution, as above, indicated thechromiumfluorocarbon complex was a very effective moisture repellant inthe border menstrual fluid control element 6', or the like. The complexcompound is approved by the Food and Drug Administration for contactwith food, in food package (Federal Register, Title 21, Part121.2518-Aug. 7,1961) A wt percent of zinc stearate in butyl stearate isparticularly desirable for a pair of waste fluid flow control elements77 and 78, or the like, applied as inch wide control elements to acontinuous web of disposable diapers during the manufacturing process.

The above chromium (Cr complex of the fluoroglycine derivative can alsobe used in the stated formulation to impregnate 2-4 plies, or the like,of 9-1 1 lb. absorbent tissue paper sheet stock. The dried, impregnatedtissue stock can then be used as the equivalent of the thin impermeableplastic film 13 of FIG. 2. Typically, a four-ply tissue sheetimpermeable film equivalent to 13 may have 0.0025 g of waterproofingfluoroglycine derivative per napkin. The completed napkin, having theimpregnated water resistant tissue ply without an impermeable plasticfilm 13, is now quite resistant to aqueous dye fluids penetrating theexterior water resistant tissue ply, in comparison with a similar napkinhaving no water resistant tissue ply. The impregnated water resistanttissue sheets disposed on the napkin exterior have the distinctadvantage of still being porous, as measured by blowing smoke throughthe water resistant tissue. Due to thesmall air cell size ,of the waterresistant tissue paper sheet, as compared Obviously many modificationsand variations in the waste fluid flow control element can be made inthe light of this teaching. Itis therefore understood that within thescope of the appended claims, the invention may be practiced otherwisethan as specifically described.
